BUILDING BLOCKS.

Application filed July 31, 1923.

To all whom it may concern:

Be it known that I, RAY H. GROVES, a'

citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Building Blocks, of which the'i ollowing is a specification.

My invention relates to improvements in building blocks for movable toys, in the construction of which wheels, shafts and interlocking blocks are used.

Theobjects of my invention are to furnish a toy which develops the constructive ability of children, which lends itseli to the pro duction of a large variety of structures of pleasing appearance, and in which the structures are of sufiiciently rigidity to permit a certain amount of handling.

I attain these objects with the mechanism illustrated in the accompanying drawing, in which Fig. 1 is a long block with two notches in each long edge.

Fig. 2 is a short block with one notch in two opposite edges. y

Fig. 3 is a block similar to 1, but provided with two holes.

Fig. 4 represents a shaft or an axle.

Fig. 5 is a narrow block with especially wide notches in one edge.

Fig. 6 may be designated as a tie block.

Fig. 7 is a short block having one notch and one hole.

Fig. 8 is a wheel.

Fig. 9 represents a dump carone or" the many varieties of structures in which the above named elements are employed.

Similar numerals refer to similar parts throughout the several views.

The blocks 1 are made in diiierent lengths and interlocked to form structures imilar IJ to Fig. 9, in a manner well known in the art. The blocks 2 are employed for columns in suitable places, as, for instance, to border the sides ofopenings in a wall. But to give these structures their distinctive aspect and quality, the structural members depicted in Figs. 3 to 8 have been designed and combined with the blocks 1 and 9. in various ways. Perhapsthe chief distinction is attained by the employment of the wheels 3,

'tions 9 on the boards Serial No; 654,801.

which are pressed onto the tapering ends of the shaft 4, and use-d either as medium of propulsion, or otherwise to simulate a steering wheel as shown in Fig. 9. To provide bearings for the shafts l, the blocks 5 are furnished with holes 6. The shafts 4; and blocks 5 may also be used to construct the tilting hopper of a dump car, however, in such a case the blocks 7 must be added to furnish a support for the shaft "1. The blocks 8 are chiefly utilized to hold the boards which constitute the door or the root inalinement. For this purpose the projec- 8 enter the spaces created by the notches of two adjoining boards, while the recesses 10 in the boards 8 furnish a seat for that portion of the block 1' which is reduced by the two notches on opposite edges. he tie block 11 holds two superimposed members in alinement where one of the members should happen to be without a notch, as instanc-ed by the tie block shown in the drivers seat 12 in Fig. 9. Here the side 13 of the seat interlocks with the notches 14 in member 11, but the edge of the underlying member has no notch. Yet, the seat will be prevented from shitting laterally by the raised back 15 of the tie block 11 which is wedged between the walls of the vehicle.

Having thus described my invention, I claim: i

A toy of the character described, formed from flat, rectangular structural members, having transverse notches in their edges, certain of said members having perforations near one edge, cylindrical structural me1nbers adapted to be inserted in said peritorations, wheel-shaped structural members adapted to be pressed on the ends of certain 01 the cylindrical n'i'einbe-rs,-certain of the flat rectangular structural members having perforations near one end to receive the ends of certain 01": said cylindrical members, whereby said structural members may be as sembled to form a toy of the character shown in Fig. 9.
